Simple benign breast cysts are commonly diagnosed in female breasts and may present as palpable masses. However, they are extremely uncommon in the male breast and are rarely reported in the literature. Here, we report a case of a simple benign cyst of the breast in a relatively healthy 37-year-old man. The patient initially presented with a palpable 2-3 mm tender left breast lump. Further evaluation with mammography and ultrasound revealed a mass most consistent with a simple benign cyst. However, considering the rarity of breast cysts in males, the lesion was biopsied to rule out malignancy. Pathology results from ultrasound-guided core needle biopsy demonstrated fibro-adipose tissue with a benign cyst lined by foamy cells with apocrine features, consistent with a diagnosis of a benign epithelial cyst and concordant with the radiological findings. To our knowledge, this is the youngest case of a benign breast cyst in a male that has been reported in the literature. In this case report, we discuss the typical features and presentation of breast cysts in males, associated imaging findings on mammography and ultrasound, and the necessity for pathological confirmation with biopsy in this population.
单纯性良性乳腺囊肿在女性乳房中很常见，可能表现为可触及的肿块。然而，它们在男性乳房中极为罕见，文献中也很少有报道。在此，我们报告一例相对健康的37岁男性患有单纯性良性乳腺囊肿的病例。患者最初表现为左侧乳房可触及一个2 - 3毫米的压痛性肿块。通过乳房X线摄影和超声进一步评估发现一个与单纯性良性囊肿最为相符的肿块。然而，鉴于男性乳腺囊肿的罕见性，对该病变进行了活检以排除恶性肿瘤。超声引导下粗针穿刺活检的病理结果显示为纤维脂肪组织，有一个由具有大汗腺特征的泡沫细胞衬里的良性囊肿，与良性上皮囊肿的诊断一致，且与影像学结果相符。据我们所知，这是文献报道中最年轻的男性良性乳腺囊肿病例。在本病例报告中，我们讨论了男性乳腺囊肿的典型特征和表现、乳房X线摄影和超声相关的影像学表现，以及在该人群中通过活检进行病理确诊的必要性。
